在装有1公斤小麦的圆盘内,用培养皿测试某些植物油对谷象Sitophilus granarius L.的诱虫性或驱虫性。与矿物油比较,冷榨未提炼的燕麦油,能量油(混合油)麦芽油,芥籽油,有强的诱虫性(P<0.05),而提炼后的燕麦油有强的驱虫性;新鲜的麦芽油和能量油的诱性优于各自陈化的油。向日葵油分别与麦芽油,南瓜籽油,红花油等量混合,其诱性降低,而与提炼的燕麦油、芝麻油、或棉籽油与芝麻油,提炼燕麦油等混合,其驱虫性将增加。 相似文献

Bamboo residues were liquefied in a mixture of glycerol and methanol in the presence of sulfuric acid using microwave energy. We investigated the effects of liquefaction conditions, including glycerol/methanol ratio, liquefaction temperature, and reaction time on the conversion yield. The optimal liquefaction conditions were under the temperature of 120 °C, the reaction time of 7 min, the glycerol–methanol–bamboo ratio of 8/0/2(W/W), and the microwave power of 300 W. Maximum conversion yield was 96.7 %. The liquid products were separated into two contents(water soluble part and precipitate part) by addition of a sufficient amount of water. By Fourier transform infrared(FT-IR), the water soluble content mainly contained glycerol and its derivate and carbohydrate degradation products, and the precipitate content was mainly lignin derivatives. 相似文献

利用RAPD标记鉴定大豆种质 总被引:49,自引:4,他引:49
本研究以57个中国大豆祖先吕系及育成品种和18个美国大豆祖先品系为DNA样品来源,通过随机引物PCR扩增基因组DNA的多态性,探索利用RAPD标记鉴定和相关种质的可能性。研究结果表明,50个10摩尔随机引物共扩增可分辩产物246个,其中82.4%的随机引物可产生多态性产物,所扩增产物的54.4%至少在两个基因毒草境存在差异。上PCR扩增产物分别以1和0记录存在与否。扩增产物间的成对比较可产生非相似 相似文献
